SKEIN-DYEING MACHINE.

tion, the yarn `being completely submerged during such motion. Means areprovided @as an object of the invention to intermittently shift theposition ot the yarn `on the rolls for each stroke up and down of the`yarn support. l

A Yfurther object is to render the `supporting frames interchangeablewith regard to the tanks, thereby permitting a continuous process ofdyeing.

Other objects of the invention will appear as the description proceedsand from the drawings and claims.

The invention consists li-n the features, combination and arrangementofparts .hereinafter set forth and particilhtrly pointed out in theclaims.

In the accompanying drawings Figure l is a 'front elevation partly insection of the dyeing machine and tank.

Fig. 2 is a sectional elevation of Fig. 1.

Fig. 3 is a view of the ratchet mechanism for intermittently driving therolls. Fig. 3 an end view of Fig. 3.

Figs. 4 and 4 are views of the `guide T.

Referring to the drawings, A represents a tank or vat constructed ofwood `which may be metal lined to render it suitable for `the resistanceto such acids as it might come in contact with. rlhe rectangular tank orvat A is provided at its ends with oppositely disposed and aligneduprights or bearing supporting columns C.

Bearings C are provided atthe top of the columns for receiving the endsof ashalt Q upon which shai't 'the entire yarn simporting traine B Aishung.

The basket or `frame B is prefe `ably con structed of Mone] metal, orother acid resisting metal and is `rectangular in `structure with topand bottom rails, a and b which support bearings `c which in turnsupport bottom or lower rolls D and upper rolls E, `also constructed ofacid resisting metal or wood.

` The rolls D and E each consist of a tubulail `metal shaft d with ametal disc e at each `end and metal slats f connecting the discs. The`top rolls E are constructed in the same way as the `bottom rolls exceptthat the .driven end g of the rolls has a tapered square projection lafor receiving the driver la An inverted V-shaped truss/m, formed at eachend of the frame B and at the apex of each truss a hanger n is pivoted.The upper ends `of the hangers .a are connected with eccentrics p, oneeccentric being adjacent each end of the shaft Q.

The shaft Q, rests in the bearings C and is rotated by any suitablemeans such as a gear wheel g which is connected through reductiongearing r with motor s mounted on a bracket attached to the tank. As theshaft 1Q is rotated an oscillating up and down motion is imparted by theeccentrics to the yarn carrying frame.

A stationary rod L is hung from shaft Q by means of sleeve t at itsupper end. At its lower end rod L carries a crosshead O which has ascrew threaded `connection therewith. Links N pivotally connected toopposite sides ot cross-head O are pivotaliy `connected at their lowerends to rods J which a.realigned but are adapted to move in op positedirections upon relative vertical movementbetween the cross-head andframe.

Rods JV pivotally carry depemling pawl members I `at spaced intervalsalong their length corresponding to the spacing between the rolls The`pawl members I each have a yieldable spring pressed pawl 7c at theirlower `ends adapted to cooperate with teeth 7c `on drive wheels to turn`rolls E.

The pawl members I have .openings 4 and are pivotally received on driveWheels 7c in rear `of teeth Vc as shown at 5 in Fig. 3, and when swungin one direction `will turn drive wheels 7c by means of awls k2 and whenswung in the opposite cirection will move freely about Vdrive wheels kwith. ipawls Ail `slipping over the teeth. lo. Drive wheels t aresecured on the tapered square projection `hon each of the upper rolls E.

As the shaft Q is rotated the eccentrics cause the frame to beoscillated up and down which produces relative movement betweenstationary rod L and the frame and causes the rods J through links N tomove .laterally relative to the frame and to cause pawl menibers I, thepawls 7a2 of which are in engagement with teeth lc', to turn the rolls Ethus moving the yarn for a short distance.

A guide P is secured to the truss m adjacent the rod L and receives therod vL to guide the frame in its reciprocating motion relative thereto.AA lift frame S is mounted on the shaft Q to rotatably7 receive thesame.

The skeins or hanks of yarn are placed one on each roll Eand extend downinto the dye-liquor and support corresponding rolls D. The rolls D arekept in place by having their stub ended shafts d in engagement withslotted bearings c, these bearings being of sufficient length toaccommodate different lengths'of skein or hank yarn.

Guard rods K are provided to prevent the yarn from getting over too nearthe end of the roll. M is a steam coil in the bottom of the tank.

' reduction gearing. In this way a continu-` As the shaft Q is rotated,the eccentrics cause the frame to reciprocate up and down on guides T ateither end of the tank, the

tank being of sufficient depth to keep the skein or liank completelysubmerged during the process. Upon each reciprocation of theframerelative vertical motion takes place between the frame and rod L,causing movement of links N and rods J to operate the pawls and ratchetscausing the rolls E to rotate for a part of a turn. This motion istransmitted to rolls D and the whole hank or skein shifts position whenthe roll E turns. i

The frame or .basket is interchangeable with other tanks of likedimensions by simply lifting the frame out of the tank, and moving it tothe next tank by means of a trolley and setting it down over the guidesT and causing the gear on the end of the drive shaft Q to mesh with apinion of the ous processI is permitted by transferring the basket androlls from tank to tank while loaded with skein, for boiling out,degumming, dyeing, rinsing or softening.

Figs. 4 and 4 show the spaced apart angle iron construction of the part1 of the guide T which is secured to the tank by plates 2.

Cooperating angle iron guide part 3 is ay part of frame B and extends upand attaches to rod N and is spaced wide enough to slipfreely on guidepart l. p

I claim:
